Description

DETAILED DESCRIPTION OF THE INVENTION (1) Description of the field to which the invention pertains The present invention relates to a method for creating document information containing a mixture of characters and graphics, which is simple and easy to operate.

(2) Description of the prior art The conventional document editing method mainly uses a graphic display on which figures can be entered. First, figure information is input using a facsimile, etc., displayed on the graphic display, and then inputted using a keyboard, etc. You can add character information using a character code input device to create a mixed document of character information and graphic information, or you can use a facsimile device with a display that only allows input of character codes, and use the display for the character information part. The method can be roughly divided into two methods: creating a mixed screen by inputting the graphic information part from a facsimile.

However, although the former method is convenient from an operator's perspective, it has the disadvantages of requiring a large amount of memory for graphic information and an expensive graphic display, and is not suitable for high-end systems. It is not used unless it is a special case.

In addition, in the latter method, the figure information part is created by inputting it into a facsimile without displaying anything on the display, and special mark information is placed around the figure in order to cut out the figure information part necessary for editing. In addition, the facsimile device also needs a detecting section for the mark information, and furthermore, a code for specifying the insertion point of graphic information is added to the text information.
Although it is possible to use an inexpensive display, there are drawbacks such as poor operability for the operator.

(3) Purpose of the Invention In order to eliminate these drawbacks, the present invention uses a conventionally used display that only displays character codes, displays graphic information in a roughness necessary for editing processing, and displays the This allows mixed information to be created and transferred while viewing graphical information, and is intended to be inexpensive and to improve operability for the operator.

This will be explained below with reference to the drawings.

(4) Description of the structure and operation of the invention FIG. 1 shows a conceptual diagram of a method for editing a document containing a mixture of characters and figures. In Figure 1a,
1 is a graphic information input section. This is realized by the function of the facsimile transmitter. 2 is a character code information input section. This is accomplished using a keyboard or the like.
3 is a display for displaying character codes. Reference numeral 4 denotes a graphic-character code conversion unit that converts graphic information into character code information. Reference numeral 5 denotes a character code information memory that stores the graphic information inputted from 1 and the character code information inputted from 2 converted into the same code format as the character code format, and the memory contents are displayed on the display 3. is displayed.

In FIG. 1b, 7 is an example of the final mixed document, and in the example 7, character code information is shown on the left and graphic information is shown on the right. Now, when editing a drawing like this 7, first a manuscript like 6 showing the drawing part is created. Next, the original 6 is input from the graphic information input section 1, and the graphic-character code conversion section 4 calculates the ratio of black information to white information in each predetermined character unit area. Accordingly, by associating specific characters with each other, the data is converted into a character code format and stored in the memory 5 in a code format similar to the character code. The information stored in the memory 5 is converted into a character pattern and drawn on the display 3, as shown in 8. The operator can input the character information shown in the document 7 from the character code information input section 2 by looking at the figure drawn on the display 3 using this character pattern.

It is sufficient for the operator to recognize the position where the drawing is inserted, and there is no need to faithfully reproduce the drawing on the display 3. Also display 3
It is not necessary that the document size to be created can be displayed in full in the area displayed.

Note that the code for the graphic information displayed on the display 3 may be provided by newly defining a specific code (for example, a full-page mark), or it may be set by newly defining a specific code (for example, a full-page mark). You may also use the included codes (for example, #, $, ¥, 〓, etc.). Alternatively, in the graphic information part, a code with a large number of strokes is assigned to a large area of black, a code with a small number of strokes is assigned to a large area of white, and a code with a small number of strokes is assigned to a part with a large area of white, and a code with a small number of strokes is assigned to a part with a large area of white. may be assigned a space code.

All of these codes are included in the concept of character code format according to the present invention.

Next, FIG. 2 will be explained. FIG. 2 is a block diagram showing the configuration of FIG. 1 in more detail.

Graphic information is input from a graphic reading section 9. This information is stored once in ten memory sections. For reading in the figure reading section 9, line scanning may be performed on the document surface in the horizontal direction like conventional facsimile scanning, or a sensor corresponding to the length of character information in the vertical direction may be prepared in advance. However, the data scanned in the vertical direction in units of character codes may be stored in the memory unit 10. here,
Let us discuss the former case. The memory unit 10 stores graphic information in units of characters and lines. Normal character pitch is expressed in the inch system and is defined by the number of characters per inch. Furthermore, line pitch is defined by the number of character lines per inch. For example, a character pitch of 10 characters/inch and a line pitch of 6 characters/line/inch are often used.

Graphic input is defined as the number of scanning lines per mm, while character code input is defined as the number of characters per inch. Therefore, in order to display graphic information on a display as character code information, the graphic information is converted into a predetermined character code according to the amount of information per character code unit. FIG. 3 shows the relationship between the contents stored in the memory section 10 after reading the graphic information and character codes. When converting from a graphic information code to a character information code, if the respective unit systems are different, resolution conversion is required to match the information stored in the memory unit 10 with the character system of the character information. In some cases, it may be done.

The contents of the memory section 10 shown in FIG. 2 are originally information to be output as a hard copy, and must be transferred as facsimile encoded information to the output section of this apparatus or a receiver at a remote location. For this purpose, graphic information is encoded by a run-length encoder of 12, stored in a graphic information memo section of 13, and then encoded by two run-length encoders via a communication control section of 21 in accordance with an instruction from a control section.
It must be transferred to the second transmission path or output section.

On the other hand, the contents of the memory section 10 are displayed on the display 20.
In order to display it as character code information, 15 code converters detect the amount of graphic information in each character area, and convert it into another character code system using 16 code tables according to a predetermined threshold. Convert to the sign of The converted code is stored in 19 character code memory sections.

An instruction to switch between the facsimile code information to be transferred to the other party's terminal and the character code conversion system to be displayed on the display 20 is given from the control section 11. This switching instruction may be such that 12 and 15 encoding is performed alternately for each character line. In this way, the graphical information in units of parts or pages is converted by the 15 code converters and displayed on the display 20, after which character information is inputted by the operator from the character input device 18 such as a keyboard.

The character code memory section 19 shown in FIG. 2 stores character codes converted from graphic information and character codes of character information input by the operator. This content is displayed on the display, and the coded part of the character information is transferred to the output unit or the other party's terminal via the communication control unit 21 together with the graphic information stored in the graphic information memory unit 13. This switching is performed by the control section 11. In addition, if the terminal on the communication partner side does not have a function to record run-length encoding information of graphic information, the graphic information and the input information of character information stored in the character code memory section 19 are stored separately. It is also possible to transmit the information alone or in combination to the other party's terminal so as to notify the general image of the figure. Of course, it is also possible to perform similar output to the output section of the own terminal.
Note that character information and character-encoded graphic information are separated in transmission using known characters, attribute information specifying graphic information, control codes, and the like.

Next, a method of converting graphic information into character codes will be explained.

Character areas 23 and 24 shown in FIG. 3 contain graphic information. In this case, the graphics can be converted into various codes for each area depending on the amount of graphic information such as the number of black pixels included in a predetermined character area. FIG. 3 shows that when, for example, an all mark code is newly defined for this purpose, the character areas 23 and 24 are converted to this mark code and the status is displayed on the display surface. Furthermore, since the character area 25 does not include graphic information, it is converted into a space code. Therefore, nothing is displayed in the "space" area on the display screen.

(5) Explanation of Effects As explained above, according to the present invention, character patterns can be added to a simple display for character codes without using an expensive graphic display and without impairing the quality of conventional graphic information transmission. Since it is possible to roughly draw and display graphical information using , and create a document containing a mixture of graphics and characters, it is possible to provide an editing processing system that is highly economical and has fewer editing errors by the operator.

In addition, the mixed information of figures and characters created in this way can be easily transferred to a communication system that handles only general character code information and output from a terminal, allowing for the diversification of processing information and the accompanying system It is possible to improve usage performance.
